Getting internal plugin error with Veetle plugins

Can anyone suggest a solution...I cannot get Veetle to work on Firefox 4.0

Any channel will stick at loading and when I try and push the power button on the player I get an error message saying "Internal plugin error"

I have tried a different browser and can get Veetle to work without any problems.

I have manually removed the following veetle plugins and reinstalled them:

Veetle TV Core 0.9.18.0
Veetle TV Player 0.9.18.0

but am still experiencing the same problem.

I am running Firefox 4.0 and had no problem watching Veetle channels, but now before the channel loads the unresponsive script pops up saying it is on a Blocklist (being from FF I imagine) and then says 'internal plugin error.'

I absolutely do not want to uninstall and reinstall Firefox like the solution says. I have yet to update to version 5 and am wondering if Veetle will play by just updating to Version 5 without uninstalling FF version 4?

Or simply...Will Veetle play on Firefox 5? Also, why did Veetle all of a sudden stop playing on FFox version 4?
